DST law changes in Egypt, Greenland, Morocco, and Palestine.
When observing Moscow time, Europe/Kirov and Europe/Volgograd now
use the abbreviations MSK/MSD instead of numeric abbreviations,
for consistency with other timezones observing Moscow time.
Also, America/Yellowknife is no longer distinct from America/Edmonton;
this affects some pre-1948 timestamps in that area.

DST law changes in Chile, Fiji, Iran, Jordan, Mexico, Palestine,
and Syria. Historical corrections for Chile, Crimea, Iran, and
Mexico.
Also, the Europe/Kiev zone has been renamed to Europe/Kyiv
(retaining the old name as a link).
The following zones have been merged into nearby, more-populous zones
whose clocks have agreed since 1970: Antarctica/Vostok, Asia/Brunei,
Asia/Kuala_Lumpur, Atlantic/Reykjavik, Europe/Amsterdam,
Europe/Copenhagen, Europe/Luxembourg, Europe/Monaco, Europe/Oslo,
Europe/Stockholm, Indian/Christmas, Indian/Cocos, Indian/Kerguelen,
Indian/Mahe, Indian/Reunion, Pacific/Chuuk, Pacific/Funafuti,
Pacific/Majuro, Pacific/Pohnpei, Pacific/Wake and Pacific/Wallis.
(This indirectly affects zones that were already links to one of
these: Arctic/Longyearbyen, Atlantic/Jan_Mayen, Iceland,
Pacific/Ponape, Pacific/Truk, and Pacific/Yap.) America/Nipigon,
America/Rainy_River, America/Thunder_Bay, Europe/Uzhgorod, and
Europe/Zaporozhye were also merged into nearby zones after discovering
that their claimed post-1970 differences from those zones seem to have
been errors.
While the IANA crew have been working on merging zones that have no
post-1970 differences for some time, this batch of changes affects
some zones that are significantly more populous than those merged
in the past, notably parts of Europe. The loss of pre-1970 timezone
history for those zones may be troublesome for applications
expecting consistency of timestamptz display. As an example, the
stored value '1944-06-01 12:00 UTC' would previously display as
'1944-06-01 13:00:00+01' if the Europe/Stockholm zone is selected,
but now it will read out as '1944-06-01 14:00:00+02'.
There exists a "packrat" option that will build the timezone data
files with this old data preserved, but the problem is that it also
resurrects a bunch of other, far less well-attested data; so much so
that actually more zones' contents change from 2022a with that option
than without it. I have chosen not to do that here, for that reason
and because it appears that no major OS distributions are using the
"packrat" option, so that doing so would cause Postgres' behavior
to diverge significantly depending on whether it was built with
--with-system-tzdata. However, for anyone for whom these changes pose
significant problems, there is a solution: build a set of timezone
files with the "packrat" option and use those with Postgres.

The generated resource files aren't exactly the same ones as the old
buildsystems generate. Previously "InternalName" and "OriginalFileName" were
mostly wrong / not set (despite being required), but that was hard to fix in
at least the make build. Additionally, the meson build falls back to a
"auto-generated" description when not set, and doesn't set it in a few cases -
unlikely that anybody looks at these descriptions in detail.

Autoconf is showing its age, fewer and fewer contributors know how to wrangle
it. Recursive make has a lot of hard to resolve dependency issues and slow
incremental rebuilds. Our home-grown MSVC build system is hard to maintain for
developers not using Windows and runs tests serially. While these and other
issues could individually be addressed with incremental improvements, together
they seem best addressed by moving to a more modern build system.
After evaluating different build system choices, we chose to use meson, to a
good degree based on the adoption by other open source projects.
We decided that it's more realistic to commit a relatively early version of
the new build system and mature it in tree.
This commit adds an initial version of a meson based build system. It supports
building postgres on at least AIX, FreeBSD, Linux, macOS, NetBSD, OpenBSD,
Solaris and Windows (however only gcc is supported on aix, solaris). For
Windows/MSVC postgres can now be built with ninja (faster, particularly for
incremental builds) and msbuild (supporting the visual studio GUI, but
building slower).
Several aspects (e.g. Windows rc file generation, PGXS compatibility, LLVM
bitcode generation, documentation adjustments) are done in subsequent commits
requiring further review. Other aspects (e.g. not installing test-only
extensions) are not yet addressed.
When building on Windows with msbuild, builds are slower when using a visual
studio version older than 2019, because those versions do not support
MultiToolTask, required by meson for intra-target parallelism.
The plan is to remove the MSVC specific build system in src/tools/msvc soon
after reaching feature parity. However, we're not planning to remove the
autoconf/make build system in the near future. Likely we're going to keep at
least the parts required for PGXS to keep working around until all supported
versions build with meson.

Make our copy of the IANA timezone library use named parameters in
function declarations. Also make sure that parameter names from each
function's declaration match corresponding definition parameter names.
This makes the timezone code follow Postgres coding standards. The
value of having a consistent standard everywhere seems to outweigh the
cost of keeping the function declarations in sync with future IANA
releases.

Several backend-side loops scanning one or more directories with
ReadDir() (WAL segment recycle/removal in xlog.c, backend-side directory
copy, temporary file removal, configuration file parsing, some logical
decoding logic and some pgtz stuff) already know the type of the entry
being scanned thanks to the dirent structure associated to the entry, on
platforms where we know about DT_REG, DT_DIR and DT_LNK to make the
difference between a regular file, a directory and a symbolic link.
Relying on the direct structure of an entry saves a few system calls to
stat() and lstat() in the loops updated here, shaving some code while on
it. The logic of the code remains the same, calling stat() or lstat()
depending on if it is necessary to look through symlinks.

Invent a new flag bit HASH_STRINGS to specify C-string hashing, which
was formerly the default; and add assertions insisting that exactly
one of the bits HASH_STRINGS, HASH_BLOBS, and HASH_FUNCTION be set.
This is in hopes of preventing recurrences of the type of oversight
fixed in commit a1b8aa1e4 (i.e., mistakenly omitting HASH_BLOBS).
Also, when HASH_STRINGS is specified, insist that the keysize be
more than 8 bytes. This is a heuristic, but it should catch
accidental use of HASH_STRINGS for integer or pointer keys.
(Nearly all existing use-cases set the keysize to NAMEDATALEN or
more, so there's little reason to think this restriction should
be problematic.)
Tweak hash_create() to insist that the HASH_ELEM flag be set, and
remove the defaults it had for keysize and entrysize. Since those
defaults were undocumented and basically useless, no callers
omitted HASH_ELEM anyway.
Also, remove memset's zeroing the HASHCTL parameter struct from
those callers that had one. This has never been really necessary,
and while it wasn't a bad coding convention it was confusing that
some callers did it and some did not. We might as well save a few
cycles by standardizing on "not".
Also improve the documentation for hash_create().
In passing, improve reinit.c's usage of a hash table by storing
the key as a binary Oid rather than a string; and, since that's
a temporary hash table, allocate it in CurrentMemoryContext for
neatness.

This changes zic's default output format from "-b fat" to "-b slim".
We were already using "slim" in v13/HEAD, so those branches drop
the explicit -b switch in the Makefiles. Instead, add an explicit
"-b fat" in v12 and before, so that we don't change the output file
format in those branches. (This is perhaps excessively conservative,
but we decided not to do so in a12079109, and I'll stick with that.)
Other non-cosmetic changes are to drop support for zic's long-obsolete
"-y" switch, and to ensure that strftime() does not change errno
unless it fails.
As usual with tzcode changes, back-patch to all supported branches.

We had two occurrences of "Mitteleuropäische Zeit" in Europe.txt,

While here, correct a couple of other trivial inconsistencies between
the Default file and the supposedly-matching entries in the *.txt
files, as exposed by some checking with comm(1). Also, add BDST to

None of this has any direct functional effect.

The IANA tzcode library has a feature to read a time zone file named
"posixrules" and apply the daylight-savings transition dates and times
therein, when it is given a POSIX-style time zone specification that
lacks an explicit transition rule. However, there's a problem with
that code: it doesn't work for dates past the Y2038 time_t rollover.
(Effectively, all times beyond that point are treated as standard
time.) The IANA crew regard this feature as legacy, so their plan is
to remove it not fix it. The time frame in which that will happen
is unclear, but presumably it'll happen well before 2038.
Moreover, effective with the next IANA data update (probably this
fall), the recommended default will be to not install a "posixrules"
file in the first place. The time frame in which tzdata packagers
might adopt that suggestion is likewise unclear, but at least some
platforms will probably do it in the next year or so. While we could
ignore that recommendation so far as PG-supplied tzdata trees are
concerned, builds using --with-system-tzdata will be subject to
whatever the platform's tzdata packager decides to do.
Thus, whether or not we do anything, some increasing fraction of
Postgres users will be exposed to the behavior observed when there
is no "posixrules" file; and if we do nothing, we'll have essentially
no control over the timing of that change.
The best thing to do to ameliorate the uncertainty seems to be to
proactively remove the posixrules-reading feature. If we do that in
a scheduled release then at least we can release-note the behavioral
change, rather than having users be surprised by it after a routine
tzdata update.
The change in question is fairly minor anyway: to be affected,
you have to be using a POSIX-style timezone spec, it has to not
have an explicit rule, and it has to not be one of the four traditional
continental-USA zone names (EST5EDT, CST6CDT, MST7MDT, or PST8PDT),
as those are special-cased. Since the default "posixrules" file
provides USA DST rules, the number of people who are likely to find
such a zone spec useful is probably quite small. Moreover, the
fallback behavior with no explicit rule and no "posixrules" file is to
apply current USA rules, so the only thing that really breaks is the
DST transitions in years before 2007 (and you get the countervailing
fix that transitions after 2038 will be applied).
Now, some installations might have replaced the "posixrules" file,
allowing e.g. EU rules to be applied to a POSIX-style timezone spec.
That won't work anymore. But it's not exactly clear why this solution
would be preferable to using a regular named zone. In any case, given
the Y2038 issue, we need to be pushing users to stop depending on this.
Back-patch into v13; it hasn't been released yet, so it seems OK to
change its behavior. (Personally I think we ought to back-patch
further, but I've been outvoted.)

I forgot that INT64_FORMAT can't be used with sscanf on Windows.
Use the same trick of sscanf'ing into a temp variable as we do in
some other places in zic.c.
The upstream IANA code avoids the portability problem by relying on
<inttypes.h>'s SCNdFAST64 macro. Once we're requiring C99 in all
branches, we should do likewise and drop this set of diffs from
upstream. For now, though, a hack seems fine, since we do not
actually care about leapseconds anyway.

This absorbs a leap-second-related bug fix in localtime.c, and
teaches zic to handle an expiration marker in the leapseconds file.
Neither are of any interest to us (for the foreseeable future
anyway), but we need to stay more or less in sync with upstream.
Also adjust some over-eager changes in the README from commit 957338418.
I have no intention of making changes that require C99 in this code,
until such time as all the live back branches require C99. Otherwise
back-patching will get too exciting.
For the same reason, absorb assorted whitespace and other cosmetic
changes from HEAD into the back branches; mostly this reflects use of
improved versions of pgindent.
All in all then, quite a boring update. But I figured I'd get it
done while I was looking at this code.

Thomas Munro fixed a longstanding annoyance in pg_bsd_indent, that
it would misformat lines containing IsA() macros on the assumption
that the IsA() call should be treated like a cast. This improves
some other cases involving field/variable names that match typedefs,
too. The only places that get worse are a couple of uses of the
OpenSSL macro STACK_OF(); we'll gladly take that trade-off.

stdint.h belongs to the compiler (as opposed to inttypes.h), so by
requiring a C99 compiler we can also require stdint.h
unconditionally. Remove configure checks and other workarounds for
it.
This also removes a few steps in the required portability adjustments
to the imported time zone code, which can be applied on the next
import.
When using GCC on a platform that is otherwise pre-C99, this will now
require at least GCC 4.5, which is the first release that supplied a
standard-conforming stdint.h if the native platform didn't have it.

Backpatch-through: update all files in master, backpatch legal files through 9.4

When maintaining or merging patches, one of the most common sources
for conflicts are the list of objects in makefiles. Especially when
the split across lines has been changed on both sides, which is
somewhat common due to attempting to stay below 80 columns, those
conflicts are unnecessarily laborious to resolve.
By splitting, and alphabetically sorting, OBJS style lines into one
object per line, conflicts should be less frequent, and easier to
resolve when they still occur.

IANA tzcode release 2019b adds an option that tells zic not to emit
the old 32-bit section of the timezone files, and to skip some other
space-wasting hacks needed for compatibility with old timezone client
libraries. Since we only expect our own code to use the timezone data
we install, and our code is up-to-date with 2019b, there's no apparent
reason not to generate the smallest possible files.
Unfortunately, while the individual zone files do get significantly
smaller in many cases, they were not that big to begin with; which
means that no real space savings ensues on filesystems that don't
optimize small files. (For instance, on ext4 with 4K block size,
"du" says the installed timezone tree is the same size as before.)
Still, it seems worth making the change, if only because this is
presumably the wave of the future. At the very least, we'll save
some cycles while reading a zone file.
But given the marginal value and the fact that this is a new code
path, it doesn't seem worth the risk of back-patching this change
into stable branches. Hence, unlike most of our timezone-related
changes, apply to HEAD only.

pg_timezone_names() tries to avoid showing the "Factory" zone in
the view, mainly because that has traditionally had a very long
"abbreviation" such as "Local time zone must be set--see zic manual page",
so that showing it messes up psql's formatting of the whole view.
Since tzdb version 2016g, IANA instead uses the abbreviation "-00",
which is sane enough that there's no reason to discriminate against it.
On the other hand, it emerges that FreeBSD and possibly other packagers
are so wedded to backwards compatibility that they hack the IANA data
to keep the old spelling --- and not just that old spelling, but even
older spellings that IANA used back in the stone age. This caused the
filter logic to fail to suppress "Factory" at all on such platforms,
though the formatting problem is definitely real in that case.
To solve both problems, get rid of the hard-wired assumption about
exactly what Factory's abbreviation is, and instead reject abbreviations
exceeding 31 characters. This will allow Factory to appear in the view
if and only if it's using the modern abbreviation.
In passing, simplify the code we add to zic.c to support "zic -P"
to remove its now-obsolete hacks to not print the Factory zone's
abbreviation. Unlike pg_timezone_names(), there's no reason for
that code to support old/nonstandard timezone data.
Since we generally prefer to keep timezone-related behavior the
same in all branches, and since this is arguably a bug fix,
back-patch to all supported branches.

A large fraction of this diff is just due to upstream's somewhat

Missed an inttypes.h dependency in previous patch. Per buildfarm.

This corrects a small bug in zic that caused it to output an incorrect
year-2440 transition in the Africa/Casablanca zone.
More interestingly, zic has grown a "-r" option that limits the range of
zone transitions that it will put into the output files. That might be
useful to people who don't like the weird GMT offsets that tzdb likes
to use for very old dates. It appears that for dates before the cutoff
time specified with -r, zic will use the zone's standard-time offset
as of the cutoff time. So for example one might do
make install ZIC_OPTIONS='-r @-1893456000'
to cause all dates before 1910-01-01 to be treated as though 1910
standard time prevailed indefinitely far back. (Don't blame me for
the unfriendly way of specifying the cutoff time --- it's seconds
since or before the Unix epoch. You can use extract(epoch ...)
to calculate it.)
As usual, back-patch to all supported branches.
